' COMPANY, or CANTON, OHIO, n eonromrxomoraolrro This invention relates-to a cooler or heater for liquids, more particularly liquid treating apparatus vof the surface tubular type,

one example of which 'is shown in Letters tween adjacent tubing flowsurfaces capable of being efii'ectively conneeted to either or both tubes.
